BACKGROUND

In baseball, pitchers and catchers often communicate using nonverbalcues, such as hand gestures and head shakes, to select the next pitch,specifically the pitch type and pitch location. Communication isimportant before every pitch to enhance the chances of the catchercatching the pitch, which can be difficult if the pitcher throws adifferent type of pitch than the catcher expects. However, thisgesture-based communication method is susceptible to being decoded bythe opposing team so that the batter knows exactly what kind of pitch toexpect. Possible communication alternatives such as earpieces have theirown practical limitations, too. For example, earpieces are often drownedout by crowds and other ambient noise. Another important considerationis the speed of play; new solutions should not slow down the pace of thegame.

SUMMARY

In a general aspect, various embodiments of the present invention aredirected to a relatively small, signaling apparatus that is comprised ofa printed circuit board (PCB) without a wireless communication module.The apparatus utilizes a wired-based communication module, such asserial or USB communication. This wired-based communication module isused to time-synchronize two apparatuses (e.g., one for the pitcher andone for the catcher) so that they display the same random array ofalphanumeric characters at the same time. Additional apparatus may besynchronized after the first two are synchronized by connecting theadditional apparatus to one of the synchronized apparatuses via a wiredconnection. The alphanumeric characters may be programmed to switch at aregular frequency, such as every 20 seconds or other desired frequency.The display of the apparatuses simultaneously cycle through these randomalphanumeric characters to indicate a pitch key indicator, such as adigit from one through six, where the pitch key indicator is used toencode the true pitch signal. For example, a pitcher and catcher mayeach have a signaling apparatus on their glove or other article ofclothing and may glance at the device and see the random number “3”displayed and, thus, utilize “3” as the pitch key. This indicates to thepitcher and catcher that the third hand gesture shown by the catcher isthe true pitch signal, while other gestures are the decoy gestures. Inthis simplified approach, no buttons are necessary and any impact on thespeed of the game of baseball is minimized. In some embodiments, thisapparatus is attached to a glove or article of clothing via aspring-loaded clip attached to the back of the device. To help enhanceprivacy and prevent unwanted observers from acquiring the encoded signalon the apparatus, two layers of polarized film are applied over thedisplay of the device, each oriented orthogonally to each other withrespect to the direction of polarized light they block. This way, thenumber is visible when viewed from directly above the device but darkand unreadable from any other angle.

In another general aspect, the present invention is directed to aflexible communication apparatus with embedded electronics that canadhere to a leather glove, such as a baseball glove. The apparatus cancomprise a PCB that comprises a processing unit, a first communicationmodule operatively coupled to the processing unit, and amultidimensional array of light-and-button assemblies. The firstcommunication module is configured to communicate wirelessly with asecondary communication module, e.g., another, separate baseball glovethat has a similar flexible communication apparatus. That is, thecatcher's mitt could have one of the flexible communication apparatusesand the pitcher's glove could have a second flexible communicationapparatus, with the two in wireless communication to communicate pitchselections. The multidimensional array of assemblies may comprise atleast two rows and at least two columns of assemblies. Each assemblycomprises a switch and at least one light, e.g., a light-emittingdiode(s) (LED). Preferably, each assembly comprises multipledifferent-colored lights, with each light indicating a pitch type (e.g.,fastball, curveball). The assemblies are operatively coupled to theprocessing unit. Each light is configured to change a state (e.g., onand off, blink) in response to either (i) a change in state by theswitch (e.g., the switch being pressed) within the same assembly, or(ii) a received control signal, such as from similar communicationapparatus to which the apparatus is paired (e.g., a Bluetooth pairing,long-range (LoRa) communication). For example, a catcher could choose apitch location, and cycle through the pitch-type options, by cyclicallypressing the button corresponding to the desired location until thelighting pattern indicates the desired pitch type. For example, in asystem with two lights—red and green—red may indicate a fastball, greenmay indicate a curveball, both red and green may indicate a changeup,and blinking red may indicate a slider. The catcher could press thebutton corresponding to the desired location until the desired pitch isselected. With respect to selecting pitch location, a consideration canbe the perspective of the catcher compared to the perspective of thepitcher or other player on the field. When the catcher indicates a pitchlocation on their right-hand side, that manifests as a location on thepitcher's left-hand side, and vice versa. This mirrored left-rightcommunication effect can be taken into account during wirelesscommunication. With respect to selecting pitch type, one press may turnon the red light for fastball; a second press may turn on the greenlight for a curveball; a third press may turn on both lights to indicatea changeup; and a fourth press may rapidly turn red on and off toindicate a slider. Once the catcher's pitch selection is made, it maythen be communicated wirelessly (e.g., Bluetooth, LoRa communication) tothe communication apparatus on the pitcher's glove, which causes thecorresponding light(s) on the pitcher's glove to turn on, therebyindicating the catcher's pitch selection, in terms of both pitch typeand pitch location. The apparatus can comprise a vibration motor thatcan indicate, by vibrating, when a new pitch selection is received bythe apparatus. That is, for example, the apparatus in theslave/pitcher's glove can vibrate when a pitch selection from themaster/catcher's glove is received by the slave/pitcher's glove.

The PCB may be patterned and etched with copper traces as small as 100microns. The board preferably is populated with a battery, powerconditioning, a Bluetooth-enabled microprocessor, and multicolored LEDsand buttons. The PCB may be sewn into a small, e.g., 2 inch by 3 inch,pocket comprising a top layer of leather and bottom layer of fabric. Theleather can be patterned using a computer numerical control (CNC) tool,such as a laser cutter, to create windows for the light-buttonassemblies as well as to engrave logos. In some embodiments, aninjection molded silicone cover is placed over the light-buttonassemblies for environmental protection and to diffuse the LED light. Abioinspired adhesive, based off the adhesive used in nature by mussels,may be transferred to the cotton fabric. This adhesive is capable ofbinding to a multitude of materials, including the leather commonlyfound on baseball gloves. In some embodiments, the bottom layer ofcotton fabric can be replaced by other materials, such as ahook-and-loop (e.g., Velcro)-receptive fabric. In this embodiment, theadhesive is transferred not to the patch but to a disposablehook-and-loop fastener, which is then temporarily attached to the patch.

The catcher's pitch selection may be communicated to other recipients inaddition to or in lieu of the pitcher, such as other fielders, coaches,etc. In various embodiments, the array of switch-light assemblies isarranged into a 3 by 3 grid that corresponds to the “strike zone.” Bypressing a button in one of the nine zones, that zone's LED cyclesthrough different colors. The location of the LED indicates the desiredpitch location, while the color of the LED indicates desired pitch type.Lastly, to facilitate discrete communications, the LEDs are notpersistent, meaning the LEDs are only illuminated for the player whilethat player is actively holding a button. Other nonpersistent mechanismscan also be implemented, such as a simple timer.

In another general aspect, embodiments are directed to a method forproducing the communication apparatus. The method comprises, in variousembodiments, forming a PCB having thereon the processing unit, the firstcommunication module, and the multidimensional array of assemblies.

These and other benefits of the present invention will be apparent fromthe description to follow.

DESCRIPTION

An example of an apparatus 1300 for signaling according to variousembodiments of the present invention is illustrated in an exploded viewin FIG. 13 . For example, the apparatus 1300 can be a body-wearabledisplay device for communication among teammates on a sports team duringa competitive team event. The competitive team event can be a baseballgame (including similar sports such as a softball game) or othercompetitive event. For example, the competitive team event can be afootball game (e.g., to facilitate communication of a play between acoach and a player, such as, for example, a defensive captain and/orquarterback), a soccer game, a basketball game, a hockey game, a cricketgame, a volleyball game, or a lacrosse game.

The apparatus 1300 can comprise a body 1314 and a PCB 1302 operativelycoupled to the body 1314. For example, the PCB 1302 can be bonded to thebody 1314 with adhesive, fastened to the body 1314 with a fastener, sewnto the body 1314, or secured to the body 1314 in a pocket. The PCB 1302could be rigid or flexible in such an embodiment.

The body 1314 can comprise a top layer 1314 a and a bottom layer 1314 bdisposed underneath of the top layer 1314 a. The top layer 1314 a cancomprise various materials, such as, for example, leather or cottonfabric. The bottom layer 1314 b can comprise various materials, such as,for example, a polymer, leather, or cotton fabric. In various examples,the top layer 1314 a comprises leather and the bottom layer 1314 bcomprises a polymer.

The body 1314 can be configured to attach to a baseball glove, anarticle of clothing, an article of sporting equipment, or a combinationthereof. For example, the body 1314 can comprise a spring-loaded clip1346 attached to the back of the bottom layer 1314 b so that the body1314 can be releasably clipped to sporting equipment of a teammate(e.g., a baseball glove) or other clothing article. The clothing articlecan comprise a wrist band, a sweat band, a sleeve, or a combinationthereof. The body 1314 of the apparatus 1300 can also be operativelycoupled to a wrist of a teammate. For example, the body 1314 can beembedded within a wrist band of a teammate and the wrist band can beoperatively coupled to the wrist of the teammate.

The PCB 1302 can be positioned intermediate the top layer 1314 a and thebottom layer 1314 b. The top layer 1314 a and the bottom layer 1314 bcan be attached to one another to form a pocket in the body 1314, whichcan receive and secure the PCB 1302 within the body 1314. For example,the top layer 1314 a and bottom layer 1314 b can be attached by at leastone of a fastener, adhesive, and thread 1348 (e.g., sewn together).

The apparatus 1300 can comprise a display 1334, such as, for example, analphanumeric display (e.g., seven-segment digit display). The display1334 can be operatively coupled to the controller of the PCB 1302. Forexample, the display 1334 can be in electrical communication with thecontroller via an electrical route (e.g., a trace). The display 1334 canbe configured to change a state responsive to, for example, a controlsignal from the controller on the PCB 1302. For example, the display1334 may be programmed to change state at a regular frequency, such as,for example, every 20 seconds or other desired frequency. Thus, in abaseball setting, the apparatus 1300 can continually change state andmay change state before each pitch is thrown.

The display 1334 can be illuminated and can be configured to displayinformation, such as, for example, a pitch-type indicator, apitch-location indicator, a pitch-key indicator, or a combinationthereof. In various examples, the apparatus 1300 may not comprisebuttons or may comprise a minimal amount of buttons, which may minimizeany impact on the speed of the event.

The PCB 1302 can comprise various components, such as, for example, aclock, a controller, a communication module 1320, and a power switch1344. The clock is configured to generate a control frequency. The clockmay or may not comprise a crystal. The clock can be used in conjunctionwith the controller to generate the indicator on the display 1334. Thus,the indicator on the display 1334 may change at a first frequency basedon the control frequency generated by the clock. The first frequency canbe every 20 seconds, every 30 seconds, every 40 second, every 45seconds, every minute, or another desired frequency.

The controller is in communication with the clock and can comprisevarious functionality, such as, for example, a processing unitoperatively coupled to memory. The controller can be configured toestablish a communication link between the apparatus 1300 and a secondapparatus for signaling. For example, the controller of the PCB 1302 canbe operatively coupled to the communication module 1320 of the PCB 1302.The communication module 1320 can be a wired communication moduleconfigured to establish a wired communication link via a wiredcommunication protocol, and the apparatus 1300 may not comprise awireless communication module. For example, the communication module1320 can utilize serial communication (e.g., a magnetic snap connection,as illustrated in FIG. 14 ) or USB communication (e.g., USB connection,as illustrated in FIG. 13 ). In various embodiments, the communicationmodule 1320 can comprise a wireless communication module configured toestablish a wireless communication link via a wireless communicationprotocol.

Regardless of the type of communication module 1320 present on the PCB1302, the controller can be configured to time-synchronize the apparatus1300 with a second apparatus (not shown) so that the two apparatusesdisplay the same information (e.g., random alphanumeric character orother display configuration) at the same time on their respectivedisplay. For example, the controller can be configured to synchronizethe clock of the apparatus 1300 to a second clock of a second apparatus(not shown in FIG. 13 ) when the apparatus 1300 and the second apparatusare in communication via a communication link. Thus, the controlfrequency output by the clock of the apparatus 1300 and the second clockof the second apparatus can be substantially the same. By synchronizingthe clocks, the display 1334 can display information synchronously witha second display of the second apparatus based on the clock of the PCB1302. Additional apparatuses may also be synchronized by connecting theadditional apparatus to one of the synchronized apparatus via theirrespective communication module. In various embodiments, the controllercan be configured to terminate the communication link after the clock ofthe apparatus 1300 and the second clock of the second apparatus aresynchronized. The apparatus 1300 may not comprise a radio.

In various examples, the display of two or more synchronized apparatuses(e.g., one for the pitcher and one for the catcher) can simultaneouslycycle through random alphanumeric characters, such as, for example, thedigits one through six, or other display configurations in order toencode the true pitch signal in a pitch key. For example, a pitcher andcatcher may each have one of the synchronized apparatus on theirrespective glove or other article of clothing and may glance at theirrespective apparatus and see the random number “3” displayed on thedigit display. This indicates to the pitcher and catcher that the thirdhand gesture shown by the catcher is the true pitch signal, while othergestures shown by the catcher (e.g., gestures 1-2 and 4+) are the decoygestures. That way, if both the pitcher and catcher are wearing theapparatus, and the apparatuses are synchronized to display the samenumbers, both the pitcher and catcher will know the new pitch key (thatis, the refreshed number display on the apparatus) every 20 seconds (orsome other pre-specified time period) to decipher the catcher's handsignals before each pitch. That is, as explained above, if theapparatuses display “3” before a pitch, the catcher's third hand gesturecan signify the type of pitch to be thrown. Other position players couldalso wear the apparatus so that they too can be provided the key todecipher the catcher's hand signals.

It's possible that the pitcher and catcher may glance at theirrespective apparatuses one or two seconds apart and for the indicator tohave changed within that period of time, resulting in each player havinga different idea of the pitch key. Therefore, the apparatus can beprogrammed to indicate the alphanumeric character is going to change by,for example, blinking a displayed digit or blinking another component ofthe display in order to indicate that the digit is about to change, forexample, within the next three seconds. That way, both playersunderstand to wait for the alphanumeric character to change beforereading the alphanumeric character.

The pitcher and catcher do not necessarily need to have the sameapparatus configuration. The pitcher and catcher could use differentdisplay interfaces, as long as the apparatus are programmed to displaythe same number or other display configuration at the same time.

The top layer 1314 a of the apparatus 1300 can comprise an opening 1326corresponding to the digit display 1334. The opening 1326 can be formedby a tool, such as, for example, a laser cutter. The top layer 1314 acan be oriented relative to the PCB 1302 to align the opening 1326 withthe digital display 1334.

To help enhance privacy and prevent unwanted observers from acquiringthe true pitch signal, a first cover layer 1316 a can be placed over thedisplay 1334. In various examples, a second cover layer 1316 b can alsobe placed over the display 1334. Each cover layer 1316 a and 1316 b cancomprise polarized film, and each cover layer 1316 a and 1316 b can beoriented orthogonally with respect the direction of polarized light thatthe other cover layer blocks. This way, the number or other displayconfiguration on the display 1334 may only be visible when viewed fromdirectly above the apparatus 1300 and may otherwise appear dark andunreadable from other angles.

FIGS. 14A-C illustrate a body-wearable display device 1400 forcommunication among teammates on a sports team during a competitive teamevent. The device 1400 can comprise a body 1414, a PCB (not shown), adisplay 1434, and a communication module 1420. For example, the PCB canbe bonded to the body 1414 with adhesive, fastened to the body 1414 witha fastener, sewn to the body 1414, or secured to the body 1414 in apocket. The body 1414 can comprise a spring-loaded clip 1446 so that thebody 1414 can be releasably clipped to sporting equipment of a teammate(e.g., a baseball glove) or other clothing article. The spring-loadedclip 1446 can comprise a metal, a metal alloy, a polymer, or acombination thereof. For example, the spring-loaded clip 1446 cancomprise acrylonitrile butadiene styrene (ABS).

The PCB of the device 1400 can be positioned intermediate a top layer1414 a of the device 1400 and a bottom layer 1414 b of the device 1400.The top layer 1414 a and the bottom layer 1414 b can be attached to oneanother to form a pocket in the body 1414, which can receive and securethe PCB within the body 1414.

As illustrated, the communication module 1420 can comprise a magneticsnap connection comprising a first magnetic connector 1420 a and asecond magnetic connector 1420 b. Each magnetic connector is in signalcommunication with a controller of the PCB. In an embodiment, the firstmagnetic connector 1420 a can be configured to receive signals from thecontroller (R_(x)), and the second magnetic connector 1420 b can beconfigured to transmit signals from the controller (T_(x)). Asillustrated in FIG. 15 , two devices 1400 a and 1400 b can be mated suchthat the respective magnetic connectors physically contact each otherand establish a wired communication link. Utilizing a magnetic snapconnector can reduce the thickness of the device 1400 by minimizing thesize of the communication module 1420 and enable the communicationmodule 1420 of the device 1400 to auto-locate with a secondcommunication module of a second device.

Referring back to FIG. 14B, the device 1400 can comprise a battery 1450(e.g., CR2016), which can be in electrical communication with the PCB.The device 1400 can be configured in an “always on” mode, so that it maynot accidentally be turned off. Thus, the device 1400 can besynchronized once with a second device, and it may not have to besynchronized with that device again until the battery 1450 is depleted.

A method for communication among teammates on a sports team during acompetitive team event according to the present disclosure is provided.The method comprises establishing a communication link between first andsecond body-wearable display devices. Establishing the communicationlink can comprise establishing a wired communication link or a wirelesscommunication link between the first and second body-wearable displaydevices. Establishing the communication link can comprise establishing apoint-to-point wireless communication link.

While the communication link is established, clocks on each of the firstand second body-wearable display devices are synchronized. In variousembodiments, after synchronizing the clocks, the method comprisesterminating the communication link.

A first teammate during the event wears the first body-wearable displaydevice, and a second teammate during the event wears the secondbody-wearable display device. Information is synchronously displayed byeach of the first and second body-wearable display devices during thecompetitive team event. Wearing the first body-wearable display devicecan comprise operatively coupling the first body-wearable display deviceto a wrist of the first teammate, operatively coupling the firstbody-wearable display device to an article of clothing of the firstteammate, operatively coupling the first body-wearable display device toan article of sport equipment worn by the first teammate, or acombination thereof. Operatively coupling the body-wearable displaydevices can utilize a spring-loaded clip.

FIG. 7A shows a completed, communication apparatus 700, and FIG. 7Bshows a printed circuit board (PCB) 702 thereof according to otherembodiments of the present invention. As illustrated in these figures,the apparatus 700 comprises a body 714 and the PCB 702 operativelycoupled to the body 714. For example, the PCB 702 can be bonded to thebody 714 with adhesive, fastened to the body 714 with a fastener, sewnto the body 714, or secured to the body 714 in a pocket. The PCB can bea flexible PCB or a rigid PCB. In various examples, the communicationapparatus 700 can be a flexible communication apparatus.

The body 714 can be configured to attach to a baseball glove. Forexample, the body 714 can be attached to the backside wrist-strapportion a baseball glove, as illustrated in FIG. 6 , so that it is notin or near the normal catching area or “pocket” of the glove.

The body 714 can comprise a top layer 714 a and a bottom layer (notshown) disposed underneath of the top layer 714 a. The top layer 714 acan comprise various materials, such as, for example, leather or cottonfabric. The bottom layer can comprise various materials, such as, forexample, leather, cotton fabric, or a hook-and-loop fastening material(e.g., Velcro) receptive layer. In various examples, the top layer 714 acomprises leather and the bottom layer comprises cotton fabric.

The PCB 702 can be positioned intermediate the top layer 714 a and thebottom layer. The top layer 714 a and the bottom layer can be attachedto one another to form a pocket in the body 714, which can receive andsecure the PCB 702 within the body 714. For example, the top layer 714 aand bottom layer can be attached by at least one of a fastener,adhesive, and thread (e.g., sewn together).

In various examples, an adhesive layer can be operatively coupled to thebody 714, for example, the adhesive layer can be attached to the bottomlayer of the body 714. The adhesive layer may cover at least a majorityof the bottom layer of the body 714, or the adhesive may be divided intomultiple discrete areas. For example, the area on the bottom layer ofthe body 714 near the communication module 720 may be intentionally leftwithout adhesive, which can minimize radio frequency absorption from thewireless communications. The adhesive layer can be configured tosecurely attach the body 714 to a baseball glove. In various examples, ahook-and-loop fastening layer can be attached to the body 714. Forexample, the adhesive layer can be disposed onto the hook-and-loopfastening layer, and the hook-and-loop fastening layer can beoperatively coupled to the bottom layer of the body 714. The adhesivelayer can comprise a reusable adhesive, such as, for example, anadhesive based on the chemistry in mussels.

Referring to FIG. 7B, an isolated view of the PCB 702 is provided. ThePCB 702 can comprise at least one of a rigid polymer, a flexible polymerlayer, and a conductive layer. For example, the flexible polymer can bepolyimide, polyether ether ketone (PEEK), or polyester. The conductivelayer can comprise, for example, gold, silver, or copper. The PCB 702can be single sided, double sided, multilayered, or combinationsthereof. The PCB 702 can be formed by patterning the electrical routinglayout onto a substrate and etching the substrate to form the electricalrouting, which can be as small as 100 microns.

As illustrated, the PCB 702 comprises a processing unit 706, acommunication module 720, and an array of pitch selection switch-lightassemblies 704 a-i comprising a switch 722 a-i and a light(s) 724 a-i.Each switch can comprise at least two states, such as, for example, afirst state and a second state. The switch can be, for example, a buttonswitch, a toggle switch, or a rocker switch. The switch can be momentaryor latching. In examples comprising a momentary button switch, the firststate can be the open state of the switch (e.g., not depressed) and thesecond state can be the closed state of the switch (e.g., depressed).

The light(s) preferably comprise a light emitting diode(s) (LED),although other light sources could be used. Preferably, the assembliescomprise multiple LEDs, which may be discrete LEDs that are part of acomposite multicolored LED device. Each light can comprise at least twostates, such as, for example, a first state (off) and a second state(on). The lights can also change between a constant on state, a flashingstate, and changing the frequency of the flashes.

The array of assemblies 704 a-i can comprise at least two rows and atleast two columns. For example, the array of assemblies 704 a-i cancomprise three rows and three columns, with each assembly indicating acorresponding sub-zone of the strike zone (e.g., up and in, high andaway, etc.). The array of assemblies 704 a-i can be operatively coupledto the processing unit 706. For example, the light(s) of each assembly704 a-i can be in electrical communication with the processing unit 706via an individual electrical route (e.g., a trace) and each switch ofeach assembly 704 a-i can be in electrical communication with theprocessing unit 706 via an individual electrical route. Each light canbe configured to change a state responsive to, for example, either (i) achange in state by the switch within the same assembly 704 a-i, or (ii)where another apparatus (e.g., on the catcher's glove) is sending to theapparatus (e.g., on the pitcher's glove) a control signal from thecommunication module 720 that is responsive from the received signalfrom the catcher's glove. In various examples, each assembly 704 a-i cancomprise at least two lights, including a first light configured to emita first wavelength of electromagnetic radiation (e.g., red) and a secondlight configured to emit a second wavelength of electromagneticradiation (e.g., green) different from the first wavelength. In variousother examples, each assembly 704 a-i can comprise at least threelights, including the first light, the second light, and a third light,which can emit a blue light. At least two lights within each assembly704 a-i can be within the same component (e.g., a multicolored LED) ordifferent components (e.g., two or more LEDs).

The PCB 702 can be formed with individual electrical routings (e.g.,traces) according to formula 1:rows*columns*#of assemblies*(#of switch/assembly+#oflights/assembly)=#of electrical routes  Formula 1

The top layer 714 a can comprise an array of openings 726 a-icorresponding to the array of assemblies 704 a-i. The array of openings726 a-i can be formed by a tool, such as, for example, a laser cutter.The top layer 714 a can be oriented relative to the PCB 702 to align thearray of openings 726 a-i with the array of assemblies 704 a-i. Thealignment of the array of openings 726 a-i with the array of assemblies704 a-i can enable access to the switches of the assemblies 704 a-i whenthe apparatus 700 is assembled. Additionally, a logo or other featurecan be engraved into the top layer 714 a by a tool.

The communication module 720 can be operatively coupled to theprocessing unit 706 and configured to communicate with a secondarycommunication module (not shown) wirelessly. As used herein, theprocessing unit 706 and the communication module 720 can be separatecomponents or within the same component (e.g., a Bluetooth-enabledmicroprocessor). The communication module 720 can utilize wirelesscommunication protocols, such as, for example, Bluetooth wirelesstechnology, ZigBee wireless technology, or LoRa wireless technology.LoRa is a low-power, wide-area-network (LPWAN) technology standard thatuses chirp spread spectrum (CSS) radio modulation technology; otherLPWAN standards could also be used in various embodiments. In variousexamples, Bluetooth Low Energy 5.0 is used as the wireless communicationprotocol. The communication between the communication module 720 and thesecondary communication module can be unidirectional or bidirectional.

The PCB 702 can be populated with various other components, such as, forexample, a battery 708, power conditioning circuitry 710, a power switch712, and a communication port (e.g., USB).

The assemblies 704 a-i can be left exposed in the finalized apparatus,or the assemblies 704 a-i can be covered. For example, the assemblies704 a-i can be covered by a cover layer 716 disposed over the array ofassemblies 704 a-i. The cover layer 716 can comprise various materials,such as, for example, silicone. The cover layer 716 can be sprayed as acoating composition onto the assemblies 704 a-i and thereafter cured toform the cover layer 716, or the cover layer 716 can be formed as aseparate piece (e.g., molded piece) and placed over the assemblies 704a-i after forming. The cover layer 716 can be substantially transparent.For example, the cover layer 716 can enable the electromagneticradiation emitted by the lights within each assembly 704 a-i to beobserved by a user. The cover layer 716 can protect the PCB 702 from theenvironment and diffuse electromagnetic radiation emitted by the lightsin the assemblies 704 a-i.

In one general aspect, therefore, embodiments to a system with at leasttwo apparatuses for communication are described herein. One of theapparatus can be configured as a transmitter (e.g., a master), and oneof the apparatus can be configured as a receiver (e.g., slave). Invarious examples, one of the apparatus can be configured as atransmitter (e.g., a master), and at least two of the apparatus can beconfigured as a receiver (e.g., slave). In various examples, at leasttwo of the apparatus can be configured as a transmitter (e.g., amaster), and one of the apparatus can be configured as a receiver (e.g.,slave). In various examples, at least two of the apparatus can beconfigured as a transmitter (e.g., a master), and at least two of theapparatus can be configured as a receiver (e.g., slave). In variousembodiments, in a baseball game context, the master unit may be on thecatcher's glove and the slave unit could be on another glove, e.g., thepitcher's glove, to communicate the pitch selections therebetween.

In various embodiments, the communication apparatus can use theBluetooth wireless protocol (e.g., the Bluetooth Low Energy). Bluetoothuses a master-slave relationship. Each slave must be paired with itsmaster. As described herein, the communication apparatus on thepitcher's glove could be the slave and paired to the communicationapparatus on the catcher's glove, which is the master, in a case wherethe catcher makes the pitch selections (or vice versa if the pitcher ismaking the pitch selections and communicating them to the catcher). ABluetooth master can have multiple (although a relatively limited numberof) slaves, such that the master communication apparatus (e.g., on thecatcher's glove) could be in communication with and paired to additionalslaves units, which may be communication apparatus on the glove of otherfielders and/or other Bluetooth devices (e.g., mobile devices).

In other embodiments, the communication apparatus may use other wirelesscommunication protocols, such as ZigBee, Z-Wave, WiFi, or LoRacommunication. ZigBee and Z-Wave are mesh network protocols and permitmany more nodes than Bluetooth. In various embodiments, thecommunication apparatus (e.g., on the catcher's glove) could use aBluetooth protocol and transmit the pitch selection to a relay device(e.g., a gateway computer), which transmits the pitch selection, usingZigBee, Z-Wave or WiFi, for example, to a large number of recipient endunits (e.g., communication apparatus of the fielders, coaches,spectators, broadcasters, statisticians). The relay could be remote fromthe master unit (e.g., on the catcher's glove) but still withinBluetooth range. In other embodiments, the relay could be integratedinto the master communication unit (e.g., on the catcher's glove). Inthese manners, the pitch selection communication system could beextended to multiple devices, including communication apparatus on thegloves of other fielders, mobile devices of other recipients, etc. Therecipient (e.g., slave) units may be similar to the master unit in termsof style and appearance, such as shown in FIG. 7A, or could be anothertype of mobile wireless device with suitable software (e.g., apps) fordisplaying the pitch selections, such as a smartphone, tablet, laptop,smartwatch, wearable computer, etc.

In the example of a catcher's apparatus (e.g., a master) and a pitcher'sapparatus (e.g., a slave), the array of assemblies 704 a-i and/or theopenings 726 a-i can be arranged to correspond to the strike zone.Inputs from the master can be wirelessly communicated to the slave inreal time, as illustrated in FIG. 6 . By pressing a switch in a selectone of assemblies of the catcher's apparatus, the light in the assemblycan change state (e.g., cycle through different wavelengths (e.g.,colors), turn off, turn on, flash). The location of the assembly withthe light that changes state relative to the array of assemblies canindicate a desired pitch location, while the color (e.g., wavelength ofelectromagnetic radiation emitted by the light) of the light canindicate a desired pitch type (e.g., yellow=knuckle ball, green=curveball, red=fast ball, blue=changeup). The catcher's apparatus cansimultaneously communicate the state change to the pitcher's apparatus.Responsive to the communication, the pitcher's apparatus can change thestate of a light in an assembly at a corresponding location to the lightof the catcher's apparatus, thereby discretely communicating a pitchtype and location to the pitcher. For example, if a curve ball in thebottom-right corner is desired, the catcher can press the switch in thebottom-right assembly 704 i on the catcher's apparatus to cycle throughthe colors until green illuminates, which is simultaneously communicatedto the pitcher's apparatus. With respect to selecting pitch location, aconsideration can be the perspective of the catcher compared to theperspective of the pitcher or other player on the field. When thecatcher indicates a pitch location on their right-hand side, thatmanifests as a location on the pitcher's left-hand side, and vice versa.This mirrored left-right communication effect can be taken into accountduring wireless communication. In various other examples, a consistentframe of reference can be shown on the catcher's apparatus and/or thepitcher's apparatus. For example, the array of assemblies 704 a-i can bepositioned relative to an indicator for a left-handed batter's boxand/or a right-handed batter's box. For example, a schematic diagram ofan example reference frame for a pitcher's apparatus according to thepresent disclosure is illustrated in FIG. 8 . The catcher's apparatusmay be the opposite of the pitcher's apparatus (e.g., the right-handedbatter's box can be on the left relative to the array of assemblies, andthe left-handed batter's box can be on the right relative to the arrayof assemblies).

Color schemes that are color-blind friendly can also be implemented,such as reds, blues, and turquoise for deuteranopia. To facilitateconcealment of the lights, the lights can be programmed to illuminateonly while a switch is being held, or they can also be operativelycoupled to a timer (e.g., implemented by the processor). This way, whena player is not looking at the apparatus, the lights are off, which canconceal the pitch information while simultaneously saving battery life.

In various examples, to facilitate discrete communications, the lightsmay not be persistent, such as, for example, the lights may onlyilluminate while the switch is activated (e.g., a button switch is beingheld down). Other nonpersistent mechanisms can also be implemented, suchas, for example, a timer.

Other suitable user interfaces besides the 3 by 3 grid could also beused. For example, the communication apparatus can comprise otherelectronic components aside from switches and lights, or the switchesand lights can be configured in a different arrangement. For example,the user interface can comprise: a wearable computer, with a touchscreendisplay; a processor; and wireless communication circuitry, such as asmart watch or other suitable wearable computer, a flexible e-inkdisplay, and/or arrows for indicating locations.

For example, as shown in FIG. 9 , the communication apparatus 900 cancomprise a body 914 and a wearable computer 928 with a capacitivetouchscreen display, a processor, and wireless communication circuitry.In various embodiments, the wearable computer 928 could be implementedwith a smart watch, such as, for example, an Apple Watch series 4available from Apple Cupertino Calif. (e.g., without the wrist strap),as illustrated in FIG. 9 , instead of the PCB. The wearable computer 928can comprise wireless communication circuitry, a battery, a touchscreen,a display, control logic, and other electronic functions, while the body914 (e.g., leather patch) can be configured as a mechanical carrier thatcan be attached to a baseball glove or other sporting equipment via anadhesive disposed on the back (opposite the cover layer 916 shown inFIG. 9 ) of the body 914. A broad spectrum of user interfaces can beiterated on the wearable computer via software. The software can beconfigured to display appropriate interactive user interfaces tocommunicate pitch type and pitch location, as well as communicationsprotocols for communicating with other gloves or devices. In variousexamples, a pitch-type selection screen can be randomized from pitch topitch, for example, to minimize the chance of an opponent (e.g., batter,base runner, coach) observing what a catcher/pitcher may beinputting/observing.

As shown in FIG. 10 , in some examples, the communication apparatus 1000can comprise a body 1014, a PCB (not shown), and a display 1030 insteadof lights, such as, for example, a flexible e-ink display, asillustrated in FIG. 10 . The display 1030 can be a few inches wide. Thedisplay 1030 can comprise an interface 1032 that can change in real timeand can be customized. For example, the interface 1032 on the display1030 can change between interface configurations to provide additionalmenus and functionality to the communication apparatus 1000 as desired.In various examples, switches 1022 a-d can be placed proximal to thedisplay 1030 and in signal communication with the PCB in order tointeract with the display 1030. As illustrated, a pitch-type display onthe user interface 1032 can be “FB,” which can indicate a fastball;“CB,” which can indicate a curve ball; “SL,” which can indicate aslider; and “XX,” which can indicate another pitch type. The arrowdisplayed above the pitch type can indicate the pitch location. Thelocation of the pitch types relative to one another can randomly changeto minimize the chance of an opponent (e.g., batter, base runner, coach)observing what a catcher/pitcher may be inputting/observing. Pressing aswitch 1022 a-d can select the pitch type corresponding to the button,and multiple presses of the same switch can change the location of thepitch. In various examples, each switch 1022 a-d comprises amultifunction switch similar to a directional pad, and the directionpressed on the multifunction switch can indicate the location of thepitch.

It may be desirable to limit the amount of “heads-down” time, which isthe amount of time a player is looking down at the communicationapparatus and, therefore, away from the game. The display or assemblieson the communication apparatus can be configured to minimize heads-downtime.

In some examples, the communication apparatus 1100 can comprise adifferent configuration of assemblies, such as, for example, aseven-segment digit display 1134 surrounded by arrows 1104 a-d: up arrow1104 a, down arrow 1104 b, left arrow 1104 c, and right arrow 1104 d, asillustrated in FIG. 11 . The digit display 1134 and the arrows 1104 a-dcan comprise embedded switches (e.g., clickable) and can be illuminated(e.g., backlit) by a respective light. For example, a transparent arrow(e.g., laser cut acrylic) 1204 can be attached to a switch 1222 with alight 1224 adjacent to the switch 1222 as shown in FIG. 12 . Referringback to FIG. 11 , the arrows 1104 a-d can indicate the pitch location,and the digit display 1134 can indicate pitch type. The digit display1134 can decrease a learning curve for the communication apparatus 1100as a number of fingers is already used to convey pitch type between apitcher and a catcher in baseball. For example, an illuminated leftarrow 1104 c accompanied by the number “3,” as illustrated in FIG. 11can indicate a slider pitch to the left. The arrows 1104 a-d can cyclethrough different visible/color wavelengths, turn off, turn on, and/orflash. For example, one click (e.g., change in state of switch 1222) canilluminate an arrow 1104 a-d (e.g., turn on), a second click can causean arrow 1104 a-d to flash, and a third click can turn the arrow 1104a-d off. Flashing can indicate an “off-the-plate” or outside the strikezone pitch location. For example, a constant illumination of the downarrow 1104 b can indicate a low pitch location, and a blinkingillumination of the down arrow 1104 b can indicate an “in the dirt” or avery low pitch location that should be outside the strike zone. Multiplearrows 1104 a-d can be illuminated to indicate a corner pitch location,such as, for example, illuminating the up arrow 1104 a and the rightarrow 1104 d simultaneously can indicate the upper right corner as thepitch location. For the pitch type, the digit display 1134 can comprisean embedded switch or at least two embedded switches. For example, afirst embedded switch can be disposed towards the top of the digitdisplay 1134 (e.g., closer to up arrow 1104 a than down arrow 1104 b) toincrease the number on the digit display 1134, and a second embeddedswitch can be embedded towards the bottom of the digit display 1134(e.g., closer to the down arrow 1104 b than the up arrow 1104 a) todecrease the number on the digit display 1134. This can be useful whenthe current pitch type is 5 and a 4 is desired or if a desired pitchtype is accidentally passed while selecting.

The pitcher and catcher do not necessarily need to have the samedisplay. The pitcher and catcher could use different display interfaces,as long as they are programmed to translate the commands from oneinterface to display on the other.

A method for producing an apparatus for communication according to thepresent disclosure is provided. The method can comprise forming the PCBand attaching the PCB to the body. The body can comprise a top layer anda bottom layer, and the PCB can be disposed intermediate the top layerand the bottom layer. The top layer can be attached to the bottom layerby, for example, sewing the top layer to the bottom layer. An array ofopenings can be formed in the top layer, and the array of assemblies canbe aligned with the array of openings. The body can be attached to abaseball glove. An adhesive layer and/or a hook-and-loop fastening layercan be attached to the body. A cover layer can be disposed over thearray of assemblies.

Examples

As illustrated and described herein, an apparatus according to thepresent disclosure was produced in the form of a patch. The patchcomprised a PCB comprising a 3 by 3 array of assemblies, a Bluetoothenabled microprocessor, a power switch, a lithium battery, and a powerconditioning assembly. Each assembly comprised a multicolored LED and abutton switch. The patch shown in FIGS. 1A-E supported 27 individualelectrical routings.

The PCB was formed by patterning the individual electrical routings on acopper substrate using a wax printer and a copper etchant solution wasapplied to the substrate to remove exposed copper to form the individualelectrical routings. The wax was printed directly onto the PCB as shownin FIG. 1A. FIG. 1B illustrates a close-up of the electrical routinglayout for the Bluetooth enabled microprocessor.

The individual copper pads (e.g., squares) shown in FIG. 1B are 400microns in size and the copper traces are 100 microns which can enable amultitude of connections to the Bluetooth enabled microprocessor. Inselect locations where a copper trace joins a copper pad, a chamfer wasbe added to smooth the transition between the trace and pad whichincreased the mechanical strength of the joint. The PCB shown in FIGS.1A-B, was etched using a solution of 30% by volume muriatic acid and 40%by volume hydrogen peroxide, with a ratio of 1 muriatic acid to 1.5hydrogen peroxide. The PCB can be etched with various other etchants.The PCB was submerged in the solution for approximately 2-3 min to etchthe exposed copper on the substrate (e.g., copper that was not coveredin wax). The resulting PCB is shown in FIG. 1C. Referring to FIG. 1D, aKapton solder mask for the microcontroller was laser cut, aligned, andadhered to the PCB to prevent electrical shorting of adjacent tracesduring soldering and remained on the PCB under the microcontroller. Asillustrated in FIG. 1E, the remaining components, such as, a lithiumpolymer battery, power regulation assembly, assemblies of LEDs andbutton switches, and resistors were then soldered to the PCB.

As illustrated in FIG. 2 , a body comprising a top layer of leather andbottom layer of cotton fabric was formed with a pocket configured toreceive the PCB. The pocket was 2 in by 3 in. The PCB was placed in thepocket and the top and bottom layers were sewn together to seal the PCBwithin the body. Due to the soft, deformable nature of the bottom layerof cotton fabric, the power switch for the PCB was accessible andmanipulatable through the fabric layer despite not being visible. Whenstitching the two layers together, a small gap in the stitching can beleft open if a USB connector for recharging or software reprogramming isprovided on the PCB. The leather top layer was laser cut/engraved tocreate openings for the button switches and LEDs, holes for thestitching, and the logo for LifewearLabs.

A molded silicone cover layer, as illustrated in FIGS. 3A-E, can bedisposed over the button switches. A two-part 3D-printed mold, asillustrated in FIG. 3A, can be used to create a silicone cover layercomprising an egg-crate shaped array. The bottom mold was filled withclear silicone, Dow Corning Sylgard 184, and then the top mold wasaligned with and pressed into the bottom mold. As shown in FIGS. 3B-C,the silicone cover layer was formed with a 3 by 3 array of rectangularcovers that can protect the embedded electronics in the patch. Thetwo-part 3D-printed mold of FIG. 3A was formed with a nonplanar surfacefinish, which formed a surface roughness on the silicone cover layer.The surface roughness can enable diffusion of the LED light into amore-uniform glow, as illustrated in FIG. 3D, while the silicone covercan provide a tactile feel of the button switches, as illustrated inFIG. 3E.

An adhesive layer was formed and applied to the patch. For example,dopamine hydroxide was dissolved in aqueous sodium hydroxide and held atroom temperature for 15 minutes, resulting in the oxygen-mediatedalkaline polymerization of dopamine monomers. The precursor solution wasthen mixed with acrylamide, N—N′-methylenebis(acrylamide), ammoniumpersulfate, tetramethylethylenediamine, and water to initiate a freeradical mediated chain polymerization reaction. Immediately after mixingall components, the mixture was poured into a polydimethylsiloxane(PDMS)/polyurethane mold to form the final hydrogel into a desiredshape. The mixture was allowed to polymerize for greater than one hour,resulting in the formation of a hydrogel network that is covalentlylinked via N—N′-methylenebis(acrylamide) and noncovalently cross-linkedvia electrostatic interactions of the dopamine-based moieties. The solidhydrogel was then carefully removed from the PDMS/polyurethane mold,resulting in the final adhesive product, as illustrated in FIG. 4A. Theadhesive product was transferred to the bottom layer of the leatherpatch by manually bringing the substrate and adhesive product intoconformal contact for 20 minute, as illustrated in FIG. 4B. After the 20minutes of contact, a release liner that exhibits minimal adhesion tothe adhesive product was applied to the exposed surface of the adhesiveproduct, as illustrated in FIG. 4C. This liner contained a pull tab(e.g., an area of the liner that is not in contact with the adhesiveproduct) such that the user can easily grab the pull tab and cleanlyremove the liner from the adhesive product, as illustrated in FIG. 4D.

A second patch was created and both patches were attached to respectivebaseball gloves utilizing the adhesive layer, as illustrated in FIG. 6 .
